MACHINE FOR H'OOPING BARRELS. i

SPECIFICATION forming part of Letters Patent No. 490,316, dated J' anuary 24, 1893.

Application iiled October 19,1891. Serial No. 409,222. (No model.)

To afZZ whom it may concern:

Be it known that I, JOHN A. SEAMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Hooping Barrels, of which the following is a full, clear, and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specication, in which- Figure l is a plan; Fig. 2 a broken-away vertical longitudinal section; Fig. 3 a faceview of a guide-disk or plate; and Figs. 4, 5, 6, 7 and 8 detached details of the drivers.

This invention relates to that class of mechanism for mechanically driving or forcing the hoops onto barrels, kegs and vessels of a similar character. The operation is automatically performed; the different hoops being forced on from both ends of the package simultaneously. Heretofore great difficulties have been met with in doing this work mechanically for the reason that the drivers could not be made to properly adjust themselves to the increasing diameter of the vessel and any irregularities of surface that might be encountered. It has also been a difficult matter to mounta sufficient number of drivers within the circumscribed circle so that very thin metal hoops could be used and driven evenly.

The object, therefore, of this invention is to overcome these objections by providing a machine wherein the drivers have an automatic adjustment, with reference to the increasing diameter aud circumference of the vessel, as the hoops are forced on, so as to conform to any uneven surface that may be met with. The mechanism employed for operating the drivers is the same as that set forth in Letters Patent No. 376,487, issued to me the 17th, day of January 1888,

Referring to the drawings, A A represent two bedtimbers,forming the longitudinal part of the supporting-frame, and A A2 Ad A4 and A5, are the transverse parts of the frame mounted ou the bed-timbers.

B B are two horizontal endless screw-shafts running lengthwise with and arranged at a suitable height above the basetimbers. These screw-shafts have a rot-ary, but not an endwise, movement and are provided with suitl able journal-bearings in the transverse parts of the frame, as shown in Fig. l. The parts a a of these shafts have a right and left screw-thread, so that when rotated in one direction the driveieheads travel inwardly, and outwardly when the mot-ion is reversed.

B2 B3 are two crossheads mounted upon the threaded parts of the shafts B B and upon the hollow shafts B4 B5. The perforated ends of these cross heads are correspondingl threaded with reference to the threaded shafts so as to have a forward and backward movement thereon. The hollow shafts B4 and B5 are arranged between and parallel with the screw-shafts. These hollow shafts have an eudwise movement only, and that is imparted to them by means of the cross-heads mounted rigidly thereon.

The circular companion driving-heads, C C, are rigidly mounted on the inner ends of the hollow shafts by means of set screws as seen in Fig. 2. These heads carry the drivers which are mounted around the periphery of the same.

The driver-arms, D, are pivoted to the heads C, as at c2 (Fig. 2.) and are adapted to have an automatic movement away from and to- Ward the barrel. To the outer ends of the arms D are secured the inner ends of theiiat spring-arms D. These spring-arms engage loosely with the guide-hooks 0.3, forming apart of the gage-plates a4, adjustably secured to the inner faces of the disks D2, as shown in Figs. 2 and 3. The disks D2 are rigidly secured to the transverse parts of the frame, as shown in Figs. l and 2. The gage-plates a4 are provided with the elongated slots a5 through which are inserted the clam pingbolts a, thus providing for an in-and-out adjustment of the gage-plates, in setting the springs for the purpose of holding the driver-arms at the proper angle with reference to the barrel or similar vessel before engagement therewith.

To the inner ends of the respectivedriverarms is pivoted the head-block D3; (Fig. 6) the pivot-bolt ZJ passing through the central aperture, b', therein and into the aperture b2 (Fig. 5.) in the end of the driver-arms D. That portion of the bolt, h, entering the driv IOO f havingfactual contactwith the hoops.

er-arms is threaded as is the kaperture b2, so that these parts have a threaded engagement. This providesfor a transverse rocking movement of the block D3; such movement being limited by the stop b3, formed on the upperside of the block, and beveled,as atfb4, from the center outwardly on the underside, as .The head-pieces D4 (Fig. '7.) are provided with stems h5 which engage loosely with apertures h6 near the respective ends of they head-blocks. There are two of the head-pieces D4 attached to each of the series of head-blocks, as shown in Fig. 4.. Each stem b5 is provided with au elongated slot d (Fig. 7.) receiving the end of the small screwbolt d inserted through the aperture d2 in the respective ends of the head-blocks. rlhis feature permits a slight transverse rocking movement of the head-pieces D4, within the limit of the slot d or as the workmay require. By this arrangement the head-pieces have an independent adjustment with reference to the head-blocks, as well as with them, so that no matter how uneven or irregular the surface may be ya continuous contact with the hoop is assured. cured to the head-pieces D4, and are the parts These parts are curved (Fig. 8.) to correspond to they circle of the barrel.

On each side of the main driver-arms are located two short arms D5 D5, (Figs. 2 andv 4.) connected thereto by the pivot-bolt di, which provides for an up-and-down adjustment thereof. The same head-pieces D4 are inserted in these short arms and adj ustably retained therein by the crew-bolts d5. These short arms drive the quarter hoops; thus both the bilge and quarter hoops are driven from one main arm. The short arms D5, D5, are pivoted to said main arms D, D, between the pivotal points and driving ends of the latter, whereby said shorter arms will follow the main arms in their adjustment toward and from the barrel, for the purpose before described, the short and long arms engaging and driving on the barrel separate hoops simultaneously. By this arrangement the driving mechanism has a positive contact with the hoops, and readily yields to the requirements of the operation, so that the parts having direct contact with the hoops will not slip over or dig into the wood-surface of the vessel.

Motion is transmitted to the endless screwshafts, actuating the driving mechanism, by the train of gears, D6, as shown in Fig. 1, being the same as that set forth in the patent herein referred to.

The plunger-shafts E E are located inside of the hollow shafts and have an independent endwise movement with reference thereto. On the inner ends of the plunger shafts are mounted disks F provided around their peripheries with a number of lugs g, projecting toward the work, as shown in Fig. 2. These lugs pass over the ends of the vessel, the sur- The driving-plates cl3 are rigidly sef face of the disks coming in contact with and driving the end hoop at the proper time. The disks, F provided with the lugs g also bring the vessel into a centering position during the process of driving the hoops. The plunger-shafts are operated by the hand-lever G and connections, which are the same as set forth in the patent referred to. By this construction a greater number of drivers may be used than is possible under the ordinary arrangement. The drivers for the bilge and quarter hoops being mounted on the same supporting arm, the latterk follows in the pathway of the former.

yIn operation, the barrel or vessel I-I is rst Vplaced in proper position in the centering and holding-heads mounted on the plunger shafts, the revol'uble screw-threaded shafts are then set in motion and the hollow shafts moved inwardly, bringing the drivers in contact with the bilge and quarter hoops in their order; the end hoops being set up lastk by the ydriving heads coming in contact with the centering disks on the plunger-shafts. `The motion of the screw-shafts is then reversed and the drivers returned to their normal position.

Having thus described my invention what l claim as new, and desire to secure by Letters Patent, is-
